Answer 1
Answer: Hi

(6-d)(d²-5+3d) = 6d²-30+18d-d³+5d-3d² = -d³+6d²-3d²+18d+5d-30
(6-d)(d²-5+3d) = -d³+3d²+23d-30

Answer:  -d³+3d²+23d-30

i have a question with this 'The vertices of Figure ABCD are A(1, 1), B(2, 3), C(4, 3), and D(5, 1). If Figure ABCD is reflected over the line y = –1, find the coordinates of vertex B’. Enter your answers in the boxes" i would be really happy if someone told me the answer

Answers

Answer:

(2, - 5)

Explanation:

The line y = -1 is horizontal: parallel to the y-axis.

The point B (2,3) is above the line y = - 1 at a distance equal to the y-coordinate of B (y = 3) less - 1:

Δy = 3 - ( - 1) = 4

When the point B (2,3) is reflected over the line y = -1, the x-coordinate does not change.  The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.

Hence, the coordinates of the vertex B' are x = 2, y = - 5: (2, - 5).

What is the solution of x - 13 =5

Answers

If you're looking for x then it would be x=18 since you add 13 to both sides to have x alone
x-13=5
+13=+13
x =18
the answer is x=8
